We happily stumbled upon this place hiking in and around the park. The ramen is amazing, the rice is perfect, everything's is over the top delicious. You can taste thousands of years of culture in every bit. The service is very friendly as well, they are super happy to see you. I can't wait to come back and work my way all the way through the minu, top to bottom.

Ordered the spicy miso ramen and it was delicious. The mild spice was just enough, anymore and it would’ve been a little too spicy to enjoy. The service was speedy and welcoming, highly recommend.

Really good spicy mala, I ordered the mild and it was enough spiciness for me. My husband ordered the vegetarian miso. He liked it. I liked mine best but if you are vegetarian you will be happy with the miso. Friendly staff but expect a long wait if there is an event happening in the park since this is a typical SF restaurant with very little tables.

My BF and I were looking for a new ramen spot to try in our neighborhood and came across saiwaii. We were quickly greeted and seated. The server was attentive, and the food came out fast. We shared an order of the croquettes and they were fresh, hot and delicious! I ordered the vegetarian spicy miso ramen with an egg and it was perfect! Can’t wait to visit again sometime soon now that the weather is getting cooler.

Nice and cozy place in the sunset. Friendly and fast service. Both our Ramens were spicy as ordered, taste is good but little overpowering. Halfway, we were already full. Baked mussels had some weird creamy taste, would totally skip that.

Came in early on a Sunday evening so service was really fast. I definitely enjoyed the Tonkotsu ramen, especially for the price. Good noodles and broth, and fresh toppings. Didn't go for the spicy garlic version ($2 more expensive) but simply added spice powder and oil which worked pretty well. Only let down was the pork, a little bit plain in flavor. The karaage however was a bit of a disappoinment. Didn't look that good and tasted too fiirm. While it definitely has a large portion, lots of it was just deep fried coatings. Overall still a good value option for ramen on Irving.

Good place for ramen in the sunset. Flavourful tonkatsu broth. I like the spicy garlic tonkatsu ramen. The extra spicy was just the right kick I needed

Great food and service. 5 of us with five different meals and all were great. My wife got "noodles" and I got the Mapo Tofu. Even the tea was good. Great place on a cold San Francisco day.

Must try: Spicy Garlic Tonkotsu. And the Spicy Garlic Crab is out of this world! I maybe exaggerating, but it’s really delicious 😋 However, parking is scarce. The street is surrounded by lots of stores. Sometimes it takes 30mins just to find a parking space. It is worth it though 😅

Service is very friendly but in good conscience I cannot recommend the food here. Ramen tastes awful, not authentic at all—I’ve had better instant ramen. Broth is very bland and watery, like a soup concentrate mixed with water.

Had the Chicken Ramen because that's the only ramen with no pork broth. Awesome taste. I did a big mistake by ordering Extra Spicy. Please go for Medium Spicy no matter how much you love spicy food. I also had the octopus balls for the first time in my life and it was the best thing I had since ages. Melted in the mouth

Good ramen in the Outer Sunset! No need to go all the way to Japantown for your fix. Reasonable prices for good ramen and friendly service.

This is my first time at this restaurant and I have to say the food was delicious. The service was very good from the moment you walk in and get greeted to the moment you leave and are wished a good day. The atmosphere was good, and the staff was very friendly and explained the items on the menu at length for those who don't know what they are. I highly recommend you visit this place. Just be aware that it fills up quickly. I had the non spicy tonkotsu, and my girlfriend had spicy tonkotsu.

We love Saiwaii! Always order the Vegetarian Spicy Garlic Miso Ramen. Consistently comes out amazing every time. Friendly service - definitely recommend!

yesss honestly this place popped off!! the photo does not do the food justice because i started eating before i took a photo. was pleased with the miso vegan option — honestly better than i was expecting. hit the spot during a cold sf night. the potato croquette appetizer was pretty good. tasted like i thought it would. 10/10 will be coming back ❤️

We ordered the karage donburi and chicken katsu curry and both were divine! The chicken katsu curry was some of the best I’ve had in my life - that is my go to order at Japanese restaurants so I’ve tried many ;) definitely worth a visit if you are in the outer sunset.

Firstly the service is good, everyone there was attentive and nice. The appetizers were really good. We got the mushrooms and agedashi tofu. However the ramen was just ok to me, it was a little too plain.

I ordered the spicy version of ramen, for which you have to pay extra bucks, but it doesn't fulfill. The food's flavor and taste are average.
